Their demographic characteristics, BSSQ, General Adherence Scale (GAS), and the Specific Adherence Scale (SAS) questionnaires were collected. The content, structural and simultaneous validity and factor analysis were determined using GAS and SAS questionnaires. Results: According to psychometric factors including eating behaviors, fluid intake, vitamin and mineral supplement intake, fruits, vegetables, whole grain and protein intake, physical activity and dumping syndrome management, 6 factors could explain 61.5% of BSSQ. Total score of correlation matrix BSSQ with GAS and SAS were 0.36 and 0.70. For reliability, the Cronbach’s alpha coefficient was found 0.90 and Guttmann split-half coefficient was 0.78.
